If Brad Delson wants to improve, he needs to become aware of his weaknesses. These might be things like his need to bluff, his inability to manage things, or his instability. He might also want to change opinions that he's unwilling to change.
You try to balance your desire for social and professional success with your need for a stable, secure domestic life, but it's always difficult.

You should accept that your domestic life is the true basis and foundation of your development, and don't let your career pursuits become secondary.
